When officers arrived, the girl was not responsive, police said. She was taken to University Hospital, where she died hours later.

Authorities said the little girl and “three other very young children” were unsupervised at the time of the incident. They had been left unattended by a babysitter for an undetermined period of time, police said.

The cause and manner of the Naira’s death are pending an autopsy, and the investigation is ongoing.
